入选标准
- •Male or female subjects 6 to 11 years of age, as of the Screening Visit (SV)
- •A documented history of SAR to a relevant seasonal allergen (tree/grass pollen) for a minimum of two years immediately preceding the study Screening Visit (SV).
- •A demonstrated sensitivity to at least one seasonal allergen (tree/grass pollen) known to induce SAR through a standard skin prick test.
- •Other criteria apply
排除标准
- •History of physical findings of nasal pathology, including nasal polyps or other clinically significant respiratory tract malformations, recent nasal biopsy, nasal trauma (e.g., nasal piercing) or surgery, atrophic rhinitis, or rhinitis medicamentosa (all within the last 60 days prior to the Screening Visit [SV])
- •History of a respiratory infection or disorder (including, but not limited to bronchitis, pneumonia, chronic sinusitis or influenza,) within the 14 days preceding the Screening Visit (SV), or development of a respiratory infection during the Run-in Period.
- •Active asthma requiring treatment with inhaled or systemic corticosteroids and/or routine use of beta-agonists and any controller drug (e.g., theophylline, leukotriene antagonists). History of intermittent use (less than or equal to 3 uses per week) of inhaled short acting beta-agonists prior to the Screening Visit (SV) is acceptable
- •Have any conditions that are judged by the investigator to be clinically significant and/or affect the subject's ability to participate in the clinical trial
- •Other criteria apply

结局指标
主要结局
Change From Baseline in the Average Morning (AM) and Evening (PM) Subject-Reported Reflective Total Nasal Symptom Score (rTNSS) During the Two Weeks of Treatment
时间窗: Baseline (Day -4 to Day 1 predose), Days 1 (postdose) to Day 15
Reflective TNSS is an evaluation of symptom severity over the past 12 hours prior to the recording of the score. Participants (with assistance from parents/guardians/caregivers, as needed) assessed and recorded four nasal symptoms (runny nose, nasal congestion, nasal itching, and sneezing) twice daily (AM and PM) using the following scale: * 0 = absent (no sign/symptom present) * 1 = mild (sign/symptom clearly present, but minimal awareness; easily tolerated) * 2 = moderate (definite awareness of sign/symptom that is bothersome but tolerable) * 3 = severe (sign/symptom that is hard to tolerate; causes interference with activities of daily living and/or sleeping) The total TNSS scale was 0-12 with 0 representing an absence of symptoms and higher scores reflecting more severe symptoms. Baseline was defined as the average AM and PM subject-reported rTNSS over the 4 days prior to randomization.
次要结局
- Change From Baseline in the Average Morning (AM) and Evening (PM) Subject-Reported Instantaneous Total Nasal Symptom Score (iTNSS) During the Two Weeks of Treatment(Baseline (Day -4 to Day 1 predose), Days 1 (postdose) to Day 15)
